I am trying not to use formulas..

Answer :

I am pretty sure I am on the right track but my weak algebra is making it harder

u= 3x+5

u'= 3

dx in tems of u =

and

x in tems of the new intgral =

Here is the new integral!!!!!! I am going to simplify it now!!!!!!!

Factoring out the 1/3

distribute the , Notice that I can now directly integrate the function.

factor out common crap

=

plug U back in

=

simplify and dont forget to add C!!!!!!!!!!

=
